SHOREWALL-EXCLUSION(5)

NAME
exclusion - Exclude a set of hosts from a definition in a shorewall configuration file.

SYNOPSIS

!address-or-range[,address-or-range]...

DESCRIPTION

Exclusion is used when you wish to exclude one or more addresses from a definition. An exclaimation point is followed by a comma-separated list of addresses. The addresses may be single host addresses (e.g., 192.168.1.4) or they may be network addresses in CIDR format (e.g., 192.168.1.0/24). If your kernel and iptables include iprange support, you may also specify ranges of ip addresses of the form lowaddress-highaddress

No embedded whitespace is allowed.

Exclusion can appear after a list of addresses and/or address ranges. In that case, the final list of address is formed by taking the first list and then removing the addresses defined in the exclusion.

EXAMPLES

Example 1 - All IPv4 addresses except 192.168.3.4
    !192.168.3.4

Example 2 - All IPv4 addresses except the network 192.168.1.0/24 and the host 10.2.3.4
    !192.168.1.0/24,10.1.3.4

Example 3 - All IPv4 addresses except the range 192.168.1.3-192.168.1.12 and the network 10.0.0.0/8
    !192.168.1.3-192.168.1.12,10.0.0.0/8

Example 4 - The network 192.168.1.0/24 except hosts 192.168.1.3 and 192.168.1.9
    192.168.1.0/24!192.168.1.3,192.168.1.9
